Identify Polyhedra and Calculate Surface Areas

Front

What is a polyhedron?

Back

A polyhedron is a three-dimensional shape with flat polygonal faces, straight edges, and vertices.

Front

Name the types of polyhedra based on the number of faces.

Back

Polyhedra can be classified as tetrahedrons (4 faces), pentahedrons (5 faces), hexahedrons (6 faces), and so on.

Front

What is a triangular prism?

Back

A triangular prism is a polyhedron with two triangular bases and three rectangular faces.

Front

What is a rectangular prism?

Back

A rectangular prism is a polyhedron with six rectangular faces.

Front

What is a pyramid?

Back

A pyramid is a polyhedron with a polygonal base and triangular faces that meet at a common vertex.

Front

What is the surface area of a rectangular prism?

Back

The surface area of a rectangular prism is calculated using the formula: SA = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

What is the surface area of a triangular prism?

Back

The surface area of a triangular prism is calculated using the formula: SA = bh + (perimeter of base * height), where b = base area and h = height.

Front

What is a net in geometry?

Back

A net is a two-dimensional representation of a three-dimensional shape that can be folded to form the shape.

Front

How do you identify a square pyramid?

Back

A square pyramid has a square base and four triangular faces that converge at a single point (the apex).

Front

What is the difference between a rectangular pyramid and a triangular pyramid?

Back

A rectangular pyramid has a rectangular base, while a triangular pyramid has a triangular base.
